如何使用cookie使弹出窗口消失？

// 关闭弹出窗口时设置cookie
function closePopup() {
  document.cookie = "popup_status=closed; expires=Fri, 31 Dec 9999 23:59:59 GMT";
}

// 读取cookie并检查弹出窗口状态
function checkPopupStatus() {
  var popupStatus = getCookie("popup_status");
  if (popupStatus === "closed") {
    // 隐藏或移除弹出窗口的代码
  }
}

// 读取cookie的函数
function getCookie(cookieName) {
  var name = cookieName + "=";
  var decodedCookie = decodeURIComponent(document.cookie);
  var cookieArray = decodedCookie.split(';');
  for (var i = 0; i < cookieArray.length; i++) {
    var cookie = cookieArray[i];
    while (cookie.charAt(0) === ' ') {
      cookie = cookie.substring(1);
    }
    if (cookie.indexOf(name) === 0) {
      return cookie.substring(name.length, cookie.length);
    }
  }
  return "";
}
